Could the subwoofer amp somehow "take a set" or get "acclimated" to a
certain type of input through some weird electrical phenomenon? This
apparently happened to my sub after being lent to a friend for over a
year. No abuse I know of, just a high level input for all that time.

It may simply be the difference between running the bass through your
amp/receiver on its way to the sub vs. bypassing them.

It sounds fine now after a few hours playing it with my line-level
input. It's hard to pinpoint exactly when it "recovered" its clean
bass but I don't think I imagined the difference.

It's called adaptation. Nothing's changed.

Nope.

It's your ears acclimating. The difference you hear is the tonal
compensation built into many power amplifiers. By switching from the
speaker output to the RCA output, you've eliminated it.
